Image to Base64 Converter
Paste the generated code directly into HTML, CSS or JavaScript. Everything in the browser — no file ever leaves your computer.
How to use the image to Base64 converter
Just drag your image onto the area above or click to select the file. The conversion happens instantly in the browser — no upload or download to wait for. The process supports every major image format: PNG, JPG, JPEG, GIF, WebP, SVG and BMP.
Then choose the output format that best fits your needs: Data URI for direct use in any context, HTML <img> to paste into your HTML code, CSS background for stylesheets, Base64 only to integrate with APIs or scripts, or JSON for API payloads.
Click "Copy" and paste it wherever you need. No files are uploaded to servers — everything is processed locally in your browser with plain JavaScript.
Why convert an image to Base64?
Base64 encoding turns binary files into ASCII text, letting images be embedded directly in code without relying on external HTTP requests. This is especially useful in HTML emails, where image links are often blocked by email clients; in applications that need offline or CDN-independent assets; and in embedded systems where centralizing assets into a single file simplifies deployment.
By embedding images as Base64 in CSS or HTML files, you eliminate extra server requests, which can reduce load latency on pages with lots of small icons or UI elements. For SVG icons, the conversion also allows manipulation via CSS, such as changing color with filters.
Security and privacy
Unlike online tools that upload your files to external servers, this converter runs 100% client-side. Your images never leave your device. This is essential when working with sensitive images, proprietary logos, internal documents, or any asset that shouldn't be exposed to third parties.
The conversion is done using the browser's native API — the same one used by professional applications — ensuring compatibility and reliability with no dependency on external libraries or an internet connection.
